Question

3. What is the ratio of the number of molecules in 14 g CO and 28 g N2 ? (a) 1:5 (b) 2:1 (C) 3:5 (d) 1:1​

Answer 1

Answer:

Correct option is

C

1:1

1g of H = 16g of O.

Similarly 2g of H = 32g of O.

Hence, the ratio ofH:O is 1:1.

Answer 2

Answer:

The ratio of the number of moles is exactly the same of the ratio of the number of molecules in the two compounds. So your answer would be 1:2.

Hope it helps you.
